Implements	`osid.OsidSession`
Used By	`osid.forum.ForumManager`
Used By	`osid.forum.ForumProxyManager`

This lookup session defines several views: comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete result set or is an error condition isolated forum view: All reply methods in this session operate, retrieve and pertain to replies defined explicitly in the current forum. Using an isolated view is useful for managing replies with the `ReplyAdminSession`. federated forum view: All reply lookup methods in this session operate, retrieve and pertain to all replies defined in this forum and any other forums implicitly available in this forum through forum inheritence. sequestered reply viiew: All reply methods suppress sequestered replies. unsequestered reply view: All reply methods return all replies. The methods `useFederatedForumView()` and `useIsolatedForumView()` behave as a radio group and one should be selected before invoking any lookup methods.
